Bottom bar

Bottom bar

A bottom bar is a navigation bar at the bottom of an app or webpage. It’s typically a short menu with a few icons or written options for navigation — like opening a new tab or going back to the homepage. 

Bottom bars are especially common in mobile design. Apple, for example, frequently uses them in iOS apps like Safari. On mobile, vertical side menus can get squished, and the bottom of the page is much closer to a user’s thumbs than the top. It’s the best spot for both design and usability.

With the Webflow Designer, you can create a navigation system that works for your site and audience.
